Subject: [PATCH 0/5 v1] Processing java JIT dumps from containers

From: Arnaldo Carvalho de Melo <acme@...hat.com>

Hi,

	This is trying to move the needle on supporting jitdump done
from a container while perf is running from the outside, that is not
working right now.

	I tried to collect as much details on what is being done in the
commit logs to document further work that needs to be done to support
such a scenario in a streamlined way, but what in this patchkit at least
helped in a real case, allowing us to get 'perf annotate' to work and
confirm suspicions.

Arnaldo Carvalho de Melo (5):
  perf config: Fix trival typo 'an' -> 'can'
  perf jitdump: Accept jitdump mmaps emitted from inside containers
  perf namespaces: Introduce nsinfo__set_in_pidns()
  perf jitdump: Fixup in_pidns member when java agent and 'perf record' are not in the same pidns
  perf namespaces: Fixup the nsinfo__in_pidns() return type, its bool
